I remember reading "Go Dog Go" to my son, many years ago. I was getting ready to turn the page, and he started reading it before I turned it. Yes he had memorized the book.

As it turns out, this was normal for kids to do, but it also ment I needed to get some new books.

What I should have done was point to each word as he said it to emphasis the the coorlation.

It's amazing to repeatedly read books to children - and see how quickly they pick up the rhythm, words and story.
